Finally, after reading all nine books, I get to the last one in this exciting series… but, wait a minute, I’m not so sure it IS the last one! Apart from the bonus book, The Black Book of Buried Secrets, that is being released on October 26, 2010 (in which the hidden secrets and mysteries surrounding history’s most notorious family are uncovered) the ending of The 39 Clues left some unanswered questions. “Our adventures aren’t over, Dan thought. But they are for now.” So, entretemps, this series has ended but it will definitely continue sometime in the near future.

Without giving too much away, here’s what Book 10 reveals: 14-year-old Amy Cahill and her 10-year-old brother Dan are now expected not only to find the 39 clues first, but they are also commissioned to reunite their traitorous family—the same people responsible for their parents’ death. After a month of dodging bullets, running from evil cousins and getting out of impossible situations, they aren’t at all keen on forgiving and forgetting what’s been done to them. But there’s more to the 39 clues hunt than they’ve been led to believe. Even once the reader discovers what the prize at the end of the line is and what it means—power to rule the world—what’s going to happen once it’s discovered and taken possession of?

About halfway through the book, the suspense really begins and continues full speed ahead. Haddix makes use of short chapters and cliffhanger endings to keep the reader turning the pages. This was the longest of the books at over 327 pages.

The ending is satisfying but not complete, hence it may leave some readers feeling like they’re hanging suspended. I look forward to the continuation. I’ve invested time to read this series, enjoyed it tremendously, and now I understand some things better having reached this last book.

If you haven’t started reading this series yet, it’s worth it especially since Steven Spielberg is to direct the film production based on The 39 Clues. In addition, this book offers an interactive experience for kids. They can collect the cards that come with each books, play the games online and win prizes. There are over $100 000 in prizes for clue hunters. Well, The 39 Clues isn’t over and in a way I’m glad about it. What will Amy and Dan have to face now that they’ve discovered a powerful secret? We’ll soon find out!
